The plurality of second vibration dampers 220 may be located outside the plurality of first vibration dampers 210 in the left-right direction Y of the stand 100. In other words, a distance d2 between the plurality of second vibration dampers 220 may be longer than a distance d1 between the plurality of first vibration dampers 210. In this case, the distance d1 between the plurality of first vibration dampers 210 and the distance d2 between the plurality of second vibration dampers 220 are measured based on the left-right direction Y of the stand 100. The distance d2 between the plurality of second vibration dampers 220 and the distance d1 between the plurality of first vibration dampers 210 may be the same.
When the second vibration damper 220 is installed at both ends of the second base 130 extending in the left-right direction Y of the stand 100, the second base 130 may be supported more stably on the installation surface. Accordingly, the stand 100 may be not easily fallen even when an external force is applied to the stand 100 toward the rear in the front-rear direction X of the stand 100.
A detailed description of a specific structures of the first vibration damper 210 and the second vibration damper 220 will be described later.
The stand 100 may further include at least one movement preventer. Suitably, the at least one movement preventer may include a first movement preventer 310 (see
The first movement preventer 310 may be provided to reduce a gap between the first connection bracket 160 and the support bar 140. The first movement preventer 310 may be installed on the first connection bracket 160.
The second movement preventer 320 may be provided to reduce a gap between the second connection bracket 170 and the support bar 140. The second movement preventer 320 may be installed on the second connection bracket 170.
A detailed description of a specific structures of the first movement preventer 310 and the second movement preventer 320 will be described later.
When the coupling between the mount holder 150 and the support bar 140 is not firm, or the coupling between the base assembly 110 and the support bar 140 is not firm, the stand 100 may be shaken. In particular, the larger the gap between the first connection bracket 160, which connects the mount holder 150 and the support bar 140, and the support bar 140, and the larger the gap between the second connection bracket 170, which connects the base assembly 110 and the support bar 140, and the support bar 140, the greater a degree of shaking of the stand 100 may be. Such shaking of the stand 100 may cause inconvenience to a user and may lead to a safety accident. The at least one movement preventer minimizes the gap between the first connection bracket 160 and the support bar 140 or the gap between the second connection bracket 170 and the support bar 140, the shaking of the stand 100, in particular, the shaking of the support bar 140 may be effectively prevented.
The at least one vibration damper may not only dampen the vibration of the stand 100 together with the at least one movement preventer, but also enable the stable installation of the stand 100 on the installation surface regardless of the state of the installation surface. As an example, the at least one movement preventer may be elastically deformed so that the stand 100 may be stably installed on the installation surface even when the installation surface is uneven. In other words, the at least one vibration damper may dampen the vibration of the stand 100 by absorbing an external impact applied to the stand 100 and a vibration caused by the shaking of the stand 100, and may allow the stand 100 to be stably installed on the installation surface regardless of the state of the installation surface.
